LNT1H683MSEB

The LNT1H683MSEB is a Nichicon LNT series aluminum electrolytic capacitor offering 68,000 µF capacitance at 50 V in a screw-terminal radial can. Designed for general-purpose applications, it combines large bulk capacitance with high ripple-current capability for demanding power-conditioning roles.

Built to the LNT series 105°C standard and RoHS compliant, this part is supplied in cardboard packing for mass production environments and is polarized for DC applications.

Key Features

• Capacitance & Voltage — 68,000 µF (68 mF) rated at 50 V with ±20% tolerance for substantial bulk energy storage.
• High Ripple Current — Rated ripple current: 12.8 A at 120 Hz and 14.72 A at 100 kHz, supporting high-frequency and low-frequency ripple loads.
• Temperature & Endurance — Operating range −40 °C to +105 °C with a specified lifetime of 2000 hours at 105 °C under rated conditions.
• Mounting & Package — Screw terminal radial can package (φ63.5 × 120L, size L: 12 cm × D: 6.35 cm) for secure, low-inductance connections in power assemblies.
• Polarized Electrolytic — Polarized device suitable for DC filtering and bulk storage where polarity is controlled.
• Regulatory — RoHS compliant, suitable for assemblies requiring lead-restricted components.
• Production & Packaging — Cardboard packing and designated as mass production part for volume manufacturing workflows.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing in power supplies and power-conditioning modules where large capacitance and high ripple capability are needed.
• High-ripple DC circuits — Suitable for circuits with significant AC ripple on DC rails thanks to specified ripple current ratings at both 120 Hz and 100 kHz.
• Industrial electronics — Use in general-purpose industrial equipment requiring robust bulk capacitance and operation up to 105 °C.

Unique Advantages

• Substantial bulk capacitance: 68,000 µF provides large energy reserve for smoothing and transient suppression, reducing the need for parallel capacitor arrays.
• Dual-frequency ripple rating: Ripple current values given for 120 Hz and 100 kHz allow clear design decisions for both low-frequency and high-frequency applications.
• High-temperature endurance: Rated for operation up to 105 °C with a specified 2000-hour lifetime at that temperature, enabling reliable performance in warm environments.
• Screw-terminal reliability: Robust screw-terminal mounting simplifies secure connections and replacement in serviceable power assemblies.
• Series-standard consistency: Conforms to Nichicon LNT series 105 °C screw-terminal standards for predictable mechanical and electrical integration.
• RoHS-compliant production: Meets lead-restriction requirements for regulatory-driven manufacturing and procurement.

Why Choose LNT1H683MSEB?

LNT1H683MSEB targets designs that require very large bulk capacitance combined with reliable high-temperature operation and clear ripple-current specifications. Its screw-terminal radial can package and mass-production packing make it practical for integrated power supplies and industrial equipment where serviceability and throughput matter.

Choose this part when your design demands high-capacitance bulk storage, explicit ripple-current handling at both low and high frequencies, and operation up to 105 °C with a defined endurance profile from a known series family.
